1. Product description
The ACC6 Series Quartz Flexible Accelerometer is a miniaturized, high temperature and shock resistant accelerometer. The product has excellent repeatability, start-up performance, high temperature resistance, seismic performance and high reliability. It can be used for both static and dynamic tests. It is also a standard vibration sensor.
The product adopts unique miniaturization, high temperature and anti-seismic design, advanced packaging process and special circuit. The output current of the product is proportional to the input acceleration. Users can select the appropriate sampling resistance through calculation to achieve high-precision output. The built-in temperature sensor can be used to compensate the bias and scale factor and reduce the influence of ambient temperature according to the user's needs. This product has been launched since 2012, and the number of deliveries has reached thousands. After years of application, it has become a mature product, especially widely used in the measurement while drilling of oil drilling.
